As far as using boinc and setting up seti@home, that is something you should perhaps become familiar with first (on a common platform), if you are not already.

Another side note: It had been discussed around here about running boinc on a cluster, and as far as was mentioned, it cannot be done in Linux. If your OpenBSD cluster can run boinc properly across all processors and RAM, this would be very cool to know as it would give some people around here a method to put together a power-cruncher. So please keep us updated.-Dave#2
